First Claim
Patent Images
1. A blood pressure cuff comprising:
- an alignment tab having an edge;
a sleeve; and
an inflatable bladder disposed within the sleeve, the inflatable bladder including a first rectangular section having a first width, a first end and a second end, and a tapered section of increasing width extending from the second end of the first rectangular section in a direction away from the alignment tab;
wherein a length from the edge of the alignment tab to the second end of the first rectangular section is approximately equal to a minimum arm circumference for the blood pressure cuff;
wherein the blood pressure cuff is sized for a range of arm circumferences, the range including a first circumference and a second circumference, wherein the second circumference is larger than the first circumference; and
wherein the first width equals approximately one half the difference of the first circumference and the log of the first circumference (W1=(C1−
LOG(C1))/2).

Abstract
A blood pressure cuff includes an alignment tab, a sleeve, and an inflatable bladder disposed within the sleeve. The inflatable bladder includes a first rectangular section having a first width, a second rectangular section having a second width, wherein the second width is larger than the first width, and a tapered section extending between the first rectangular section and the second rectangular section. The tapered section may be linearly tapered or a curved taper. A length from an edge of the alignment tab to the second end of the first rectangular section adjacent the tapered section is approximately equal to a minimum arm circumference for the blood pressure cuff.
